The object of my'invention is to provide an improved mechanism forreadily associatmg an dissociating the two coactlng rollers of a fwringer.

The accompanying drawing illustrates my invention in an embodimentsuitable for ordinary household use.

Fig. 1 is a vertical axlalsection in partial tical section just insidethe end wall of the base or main frame, and 1 Fig. 3 is a plan on asmaller scale.

In the drawing 10 indieatesa main frame or base, conveniently formed ofsheet met-a1, and comprising hollow end standards 11,

oppositely extending aprons 12, guard wings 13 and an intermediatetrough 14 perforated in its bottom at 15.

Each end standard is provided, in a common manner, with a verticalguide, open at its upper end for the reception and support ofjlsu albearing blocks 16 of the'lower roller 17 and for the reception of usualbearing blocks 18 of the upper roller 19.

The above-described construction is wellknown in the art and, in detail,may be varied through a wide range.

Theupper' end of each standard 11 is partially closed by inwardly"extending blocks 20, 20, each of which is provided with a verticalthreaded perforation 21 within which is screwed the upper threaded endof. a de- 35 pending bolt 22, normally held against rotation in itsblock by check nut 23. Each bolt is projected through an ear 24 at, thelower end of an upwardly extending connector plate 25, one of which liesjust inside the outer end wall of one of the hollow standards 11 and theears 24 normally resting upon the heads 22' of the bolts. The upper end0 p1ate'25 lies between blocks 20. v I

Resting upon each ear 24 is the lower end 5 of a compression spring 26sleeved over a bolt 22 and initially compressed by an adjusting nut 27threaded on the bolt.

' One of the connector plates is vertically slotted at its lower end,between its ears 24 by a slot 30 through which the shaft of the lowerroller 17 may project.

"In commercial practice both connector plates will be so slotted.

Each connector plate 25 is provided, near: its upper end, on its innerface with an inwar ly projecting pin 31 upon which ispreferablyrotatably mounted a roll 32.

- An upper frame or cross piece 35, conveniently formed of sheet metaland shapedso as" 7 to sleeve over the up er ends of standards-ll hasjournaled thereln a rock shaft 40, the ends of which are exposed, and tothese ends are connected arms 41 with their outer ends in convenientaccess by the operator. The outer ends of the two arms 41 are connectedby a cross bar 42. This cross bar 42 may be omitted if. desired.

Secured to rock shaft 40, near each end and within the cross head 35, isa cam plate 45, provided with a segmental arcuate cam flange 46 adapted,by oscillation of rock shaft 40, to take under the adjacent roll 32 andthus connect the cross bar withsprings 26. The cam flange 46 may be soformed as to take under rolls 32 without initially stressing springs 26,but in practice these cam flanges are generally so formed that, whiletheir outer ends will pass freely under rolls 32, the intermediateportion of the flange will positively engage the rolls (when arms 41 arein their medial upright positions) so as to place springs 26 underslight initial compression. The precise curvature of the cam flanges 46may be varied through a wide range and departures from 'concentricitywith the axis of the rock shaft will be ordinarily so slight that nospecial means need be provided for retaining the operatin arms 41 intheir medial vertical position. nsurance to this end may be provided, ina well-known manner, by providing a shallow notch in the upper face ofeach cam flange at its middle, (not shown). 1

The cross head 35, near each end, is provided with a transverse bar 50'arranged to form seats for the upper sides of the upper roller bearingblocks 18, the parts being so proportioned that transverse bars 50 willbe in engagement with the bearing blocks 18 and goller 1-9 will be inengagement with roller 1 With the parts in the positions shown in thedrawing introduction of material between the rollers 17 and 19 willdisplace roller 19 upwardly, thus causing bearing blocks 18 to lifttransverse bars 50 and the cross head 35, thereby shifting cams 45upwardly against rolls 32 and stressing springs Rolls 32 may be properlypositioned for coaction withcam flanges 46 by axial adj ustment of bolts22, as will be readily apparent.

The up r end of each connector plate is vertica y medially slotted,asindicated at 51 to straddle the rock shaft and thus serve to take thelateral thrust of the cam flanges 46 on rolls 32. a

Beneath each apron 12 is an outwardly and downwardly inclined drain pan60 and the gap between the inner edges of these drain pans is bridged ba rocking drain pan 61 rovided at one en with a pivot pin 62 sli ablyprojected through an opening in one end wall of the base, and at theother end with a sprin ivot pin 63, the outer end of which is sli ablyprojected through an opening64 in the opposite end wall of the base, thearrangement bein the spring pivotpin may be readily retracted fromengagement with the base and thus permit the tilting drain pan to bereadily withdrawn for cleansing. g

I Thidr'ain pan at one end is provided with a" for ed projection 65,radially distanced from the axis of the pivot pins, and pro'ecti intothis fork 'is a finger 66 carried y a Sp it collar 67 frictionalljournaled on the s aft of the lower roller, t e two parts of this acollar being held in yielding frictional enknown form. I

gaglement. with the shaft by a spring clip 68 of we By rocking the rockshaft in either direction from its medial position, the cam flanges willbe withdrawn from beneath the rolls 32, thereby disconnecting the upperroller 19 from'the influence of springs 26, and the upper cross-head maythen be lifted clearfrom the base, whereupon the upper roller 19 withits bearings may be extracted. To reassem-- ble the parts, the upperroller is placed on'the lower roller with its bearing blocks 18 in theEideways in standards 11. Rock shaft 40 ing thrown to one Or the otherof its extreme position, cross bar 35 may now be sleeved down over theupper ends of standards 11 with its transverse bars overl ing thebearinghblocks 18, wheleupon, by roc ing the rock s ft to its medialposition, the cam such that a cross head having abutments for bearingblocks of the upper wringer roller, a rock shaft journaled in said crosshead and provided with means external of the cross-head by which it maybe mani ulated, and projections carried bysaid roci: shaft laterallyinterlockable in one direction with the connector plates by angularmovement of the rock shaft.

2. A wringer comprising, a base having hollow end standards, a pair ofdepending lated, and projections carried by said rock shaft laterallyinterlockable in one direction with the connector plates by angularmovement of the rock shaft.

-3.' A wringer comprising a base having hollow end standards, a pair ofdepending bolts mounted within each end standard and axially adjustabletherein, a coiled spring mounted upon each bolt within the end standard,a connector plate mounted within each end standard and engaging thesprings there- 'in, a cross-head having abutments for bearing blocks ofthe upper wringer roller, a rock shaft journaled in said ross-head andprovided with means external of the cross head by which it may bemanipulated, and projections carried by said rock Shaft laterallyinterlockable in one direction with the connector plates by angularmovement of the fock shaft. 3

' 4. A wringer comprising a hollow base, a

tiltable, pan medially mounted in the lower fulcrum with the base and topermit lateral extraction of the pan from the base.

In witness whereof, I have hereunto set my hand at Bloomington,Illinois, this 21st day of November, A. D. one thousand nine hundred andthirty-one. Y

I EDWARD ENGELQ flanges 46 will pass vunder the rolls 32,- thereby tyingthe upper roller to the springs 26.

I claim as my invention: 1. A wringer comprising, a base liav'ing hollowend standards, spring means anchored in'eachof said end standards, aconnector plate mounted in each of said standards and associated withthe adjacent spring means,
